GRAIN- DRILL.

SPECIPICATION forming part of Letters Patent No. 391,298, dated October16, 1888.

To aZZ who/n, it may concern.-

Be it known that I, HENDRIUK B. Cnasn, a citizen of the United States,residing at Havana, in the county of Mason and State of Illinois, haveinvented certain new and useful Improvements in Grain-Drills; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in grain-drills; and itconsistsin the construction and arrangement of parts, more fullyhereinafter described, and definitely pointed out in the claims.

The object of my invention is to provide a grain-drill which will besimple in its construction, positive in its action, and arranged in amanner to admit of its utility in rough as well as smooth ground withthe same effective result.

A further object of my invention is to so arrange the different parts ofa drill that the press-wheels will be allowed an independent verticalmovement, and the adjustment of the runners and flukes may beaccomplished with case and precision by the operator from his seat onthe drill.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, wherein like letters of reference indicate corresponding partsin the several views, and in which- Figure .l. is a longitudinalvertical section. Fig. 2 is a rear view. Fig. 3 is a detail view, inperspective, of a pair of runners and their spring attachment. Fig. 4 isa detail View of the operatingdever. Fig. 5 is a detail view, insection, of ajoint.

In the drawings, A represents the front frame and B the rear frame, theformer consisting of side bars, A, and cross-bars A and A, extending theentire width of the machine. The hopper or seed-box (not shown) ismounted on the forward frame, it being provided with the usual mechanismfor feeding the grain. Situated beneath the front frame and supportingthe same are the flukes D and their runners D, which are constructed inthe usual manner. In attaching the runners D to the frame A, I employ aseries of side braces, D extending up obliquely from the fluke D to thecross-bar A of frame A, at which point they are hinged or pivoted, as at(I. These braces, as shown in Fig. 3, are made integral with the fluke Don each side thereof at a point midway the length of the lluke,anddivergelaterally in opposite directions to more effectively resistlateral strain on the flukes and runners. The upper ends of the runnersD are rigidly secured between the braces D by a bolt or red, d, passingthrough their ends and secured in the said braces. By this constructionit will be seen that the runner and fluke are held firmly together andprevented from moving out of alignment. By hinging the runners to thecrossbar an independent ver tical movement is permitted them; and to atall times retain the same in their proper working position and admit oftheir being forced up in case of their coming in contact withobstructions, connecting-bars E and springs]? are employed, the formerconnecting pairs of flukes, they being secured to the rear of the sameby suitable pins, 0, passing through elongated slots 0, formed in theends of the bars, thus allowing an independent movement of each fluke.The springs F are made fast to the frame A and extend down and back tothe connecting-bars F. Their free ends, entering an aperture in thecenter of said bars, serve to force the flukes down and hold them inplace, but permit their vertical play.

The frame B is composed of a series of separate frames, B, having sidebars, I), and end bars,b, the inner ends ofthc bars b being hinged orconnected by ball-and-socketjoints or hinges b to the front frame, A, sothat an easy vertical movement of the frames may be had and aslightlateral vibration or tilting movement admitted to prevent thewrenching of the frames in case of obstructions or unevenness of theground.

Mounted on axles F, journaled on the frames B, are presswheels B, whichcorrespond in number to and are placed in alignment with the dukes, theytrailing in the furrow made by the same to press the soil on the grainin a manner well known in the art. To secure an independent verticalmovement of the wheels in the frames, the frames are made separate andThe cross-bars H, as shown in Fig. 2, are curved or bow-shaped andextend from the center of the end bars of the outer frames to thercenterof the end bars of the inner frame, their ends being pivoted to saidbars. The bar H is preferably rectangular and extends from the crown ofone of the bars H to the crown of the other bar H, and is pivoted atsaid points. This construction admits the respective frames to movevertically independent of each other, and forms a support for the seat.

I represents the inclined seat-supporting frame,consistingofparallelbars united at their upper ends and pivoted to an arm, K, on the frontframe at their lower ends. The upper ends of this frame I are supportedby the standards i, extending from the cross-bar H, heretofore referredto. The projecting arm or lever K is secured rigidly to the under sideof the front frame and projects back and slightly downward between thetwo inner frames, 13, for tilting the front frame up or down to forcethe flukes in or out, according to the requirement of the soil. Toenable the operator to readilymanipulate this arm, a bellcrank lever, L,is employed,which is fulcrumed and rigidly secured at its angle to alateral pin, 0, journaled in the lower ends of frames L, extending fromthe parallel bars of frame I. The horizontal arm of lever L extendsforward and has a link, m, pivoted on its end, which is in turn securedto the rear end of arm K. The vertical arm of the lever L is carried upand has an inclined strap, Z, secured thereto, which extends down and ismade fast to the end of thehorizontal arm of the lever. This strap lhasan elongated vertical slot, Z, formed therein about midway its length,as shown in Fig. 4, through which passes an operating-handle, 'n, thelower end of which is pivoted on the fulcrum-pin o of the lever L, itsupper end passing through the parallel bars of beam I. To enable theoperator to manipulate the said arm K with his feet and to give a moreextended movement to the lever L, the fulcrum-pin 0 of the lever isextended out beyond the sides of the frames L, and has vertical arms 0,secured rigidly thereon, extending up within reach of the operator, sothat by forcing the arms 0 back or forward the horizontal arm of thelever L is depressed or elevated, as the case may be. By thisconstruction it will be seen that the lever L is Worked either by thehandle n or the arms 0. In the former case, the handle coming in contactwith the end walls of the slot in strip Z, the handle a is thus entheirwork by the action of spring F, and in case one of said runners shouldmeet with an obstruction the spring will be compressed, and owing to thelateral slot in the end of bar E the vertical movement of'the runner ispermitted without binding or affecting the other or companion runner;or, if the runners should simultaneously meet with an obstruction thespring would be compressed, permitting them to freely travel over theobstruction and immediately force them to their normal position afterpassing over the same.

When it is desired to force the runnersinto or out of the ground, thelever L, which is attached to the arm K, is moved either up or down,thereby moving the forward frame to an upward or downward incline, asdesired.

In uniting the rear of frames B, in the manner described, I am able 'tosecure a more positive connection than has been the case heretofore inthis style of machine.

It is evident that many minor changes in the construction andarrangement of the parts of my improvement can be made and substitutedfor those shown and described without in the least departing from thenature and principle of my invention.

I am aware that rear frames have heretofore been connected in a mannerwhich allows an independent movement, and this I do not broadly claim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a grain-drill, the combination, with a frame and a pairof flakes,of a bar connecting the same and a spring connected with said bar fornormally retaining said flukes in position, substantially as described.
